design LTC3350 without external shunt design

Question

my design is follow DC1937B. 
 and supercap size is 100Fx2 with 4 stack 
 But I don't have EXTERNAL SHUNT CURRENT design. 
 I only use CAP1/2/3/4 to do balance and shunt current 
 how do I know, internal shurnt current is enought ?

Hi, 
 Having a stack of 4 series, 2 parallel of 100F caps is still OK. The charge current will still be reduced and the shunt regulator will still discharge the high cell at ~250mA and protect the caps from over charging without external shunt FETs. This will just take 2x as long to reach the float voltage.
